Diagnoses a conflation in the pre-ADR-024 spec: the OperationRegistry inherited immutability by analogy from ADR-010's HandlerRegistry (ALPN-level), but the TLS-config argument that justifies HandlerRegistry immutability does not apply to the operation registry, which lives behind a single ALPN (alknet/call). This made from_call (which discovers ops over a live connection at runtime) structurally incompatible with the blanket immutability claim. ADR-024 layers the operation registry by trust boundary: curated (Local) ops are static and immutable — the startup trust boundary is where their composition authority is granted; session (Session) and imported (FromCall etc.) ops are dynamic at their respective scopes (per-session, per-connection) — their trust boundaries are per-scope, not per-startup. The principle: immutability follows the trust boundary. Immutability is the security control for composing ops (can escalate privilege); provenance + composition authority are the controls for non-composing ops (can't escalate). The OperationEnv trait becomes the integration point (Arc<dyn OperationEnv>), following the IdentityProvider precedent (ADR-004): the CallAdapter composes the root OperationContext.env per incoming call from the active layers (curated base + connection overlay + session overlay). Children inherit the parent's composite env by Arc::clone — overlay composition happens once at the root and propagates through the composition tree. Resolves review #002 C6 (OperationContext.env type identity crisis): the field is split into scoped_env: ScopedOperationEnv (reachability data, from the registration bundle) and env: Arc<dyn OperationEnv + Send + Sync> (dispatch trait object). One field was being used as two different types (reachability set with .allows() and dispatch trait with .invoke()); Localizes W4 (hot-swap ↔ registry mutability coupling) to the connection scope: no global mutable registry to hot-swap; overlays replace naturally with connect/disconnect and session start/end. Schema-drift on reconnect is a per-connection overlay-rebuild concern, not a global hot-swap protocol. Partially addresses W3 (CallClient registry security): the registry-shape sub-question is resolved by the overlay model; the capability-exposure sub-question (what capabilities a remote peer can trigger) remains for ADR-017 — ADR-024 does not overclaim resolution there. Amends OQ-04 to scope its immutability claim to the HandlerRegistry and cross-reference ADR-024 for the operation registry. Generalizes OQ-19's session-overlay mechanism to also cover connection-scoped remote imports — both are per-scope dynamic overlays on the static curated base, using the same trait-layering mechanism.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
